The mystery only concerns them showing up clean after you edited them. As for the deleted edited posts, I did it as I do for all duplicate posts that posters don't remove. Still don't know the answer to the first mystery.

You wiped out the edited ones and the originals re-appeared. That never happened in the past. Why are the originals now separate from the edited posts? And if they are, why not wipe out the original instead of the edited one? The edited one is the obvious intended one.

I know this is confusing, so I will try to state the problem clearly. In both cases the post you edited with the note: [The message has been edited by foodie] had the exact same post (the edited one) under it without the note. So I deleted the version with the note. This left your post as you wanted it edited without the note that you had edited it. As I stated before I don't know how the clean posting appeared under the one with the edit note.
